Design Calculations OWTS
The design flow is calculated as follows for the total waste flows of the from the existing single
family residence. The waste flow from the existing residence has been served by an OWTS
permitted at the time of county permit in 2008, under County ISDS permit No. 4419 to serve
the existing 2-bedroom residence. This design is for the replacement of the older chamber
trench system that is currently compromised due to assumed partially clogged soils. The system
is exhibiting slower infiltrative capacity and reduced recovery, therefore in need of replacement.
The existing functioning 1000 gallon two compartment concrete septic tank has been pumped a
few times in recent years and is equipped with sanitary tees and concrete risers with lids
installed at the surface. The upgrade design utifizes the existing tank with the addition of new
1000 gallon septic/dosing tank with high head pump biotube vault assembly to discharge to
new full pressure dosed chamber trenches sized for 4-bedroom capacity usage. The two
existing chamber trenches were installed approximately 6 feet below the surface and will be
abandoned in place.
The treatment capacity for the repiacement system is designed for a minimum 3-bedroom
residence adequate for the existing 2-bedroom single family home that will provide additional
�]
capacity for additional usage as needed.
From the Regulation 43 usage table:
f�
Minimum population based on 2 person per bedroom for the first 3 bedrooms = 6 persons for a
total of 6 persons usage.

5ub Surface Conditions and Testing:
A subsurface soil investigation and site assessment was performed by Sopris Engineering in on
November 19, 2020. The sails in the proposed field envelope area were sampled and
characterized by application of the USDA visual/tactile s0 texture method analysis. The SOILS
below 12 inches of topsoil/fill material consist of medium dense clay loam soil with less than 2%
scattered gravel or rock content to 7 feet below the surface grades. The soils appear to be
consistent across the site from observations in the excavated profile pits.
The native soils sampled from 2-3 feet below the surface are characterized as a soil type 3

was encountered in excavations on site. Seasonal high Groundwater levels are expected to be
below 10 feet from the existing surface grades. The soils are suitable for a conventional shallow
absorption field consisting of pressure dosed gravelless infiltration chamber units in a trench
configuration.
Treatment -Soil Treatment Unit/Absorption System Design-
The treatment/absorption field is designed based an utilizing the effectiveLong Term
rm
Acceptance Rate (LTAR) for the native soils and the application of appropriate loading factors
for a soil treatment unit system utilizing pressure distribution to full pressure dosed gravelless
chamber trenches. The new treatment system and absorption field will consist of pressure
dosed distribution of septic tank effluent via a high head pump assembly to individual chamber,
trench custom perforated distribution laterals with treatment across the native coif absorptive
surface below the placed leaching chambers.
